. I To (LZZ whom it nmy cancer/7 Be it known that l, Jnuns Aostrm, of Detroit-,in the county of \Vayne and State of Michigan, have invented new and useful Iniprovcments in Tiles or Blocks for Finishing Inside \Valls; and I do hereby declare that the following is a full, clear, and exact description thercol', reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in finishing rooms with-- out the necessity of lathing and plastering, and of putting in inside partitions without st adding, sheathing, or lathi ng and plastering, vhercby all the el't'ect of hollow walls may be oliit-ained, with proper means of ventilation.

'lhe invention consists in the peculiar construction of proper tiles, and in the method of laying the same and securing the same together and to the walls of the building, as more fully hereinafter described.

lrigurc it. a section in perspective, showing a section of one side of a room finished upon a brick wall, and a section of the other side of a room formed bya partition dividing ittrom another room. Fig. 2 is a perspective of the rear side ol' one of my tiles to be applied to the inner side of the outer wall of the build ing. laig. Ii a vertical longitudinal central section through one ot'thc division-wall tiles. in the accom mnyiug drawings, which form a part otlthis speciiicatic A. represents a tile with a smooth outer fee, and provided upon its rear face with a recess, a, in order to lighten the weight 01 the tile. The tile is formed in a suitable mold under pressure, audits outer face with a filling within the outer face of a mixture of calcined plaster and sand, sawdust, or any other suitable material, whereby a large saving in the cost of the calcined plaster is efl'cctcd. .l.ro iecting from two edges of this tile are lugs b, and in the opposite edges are recesscs c 0, adapted to receive the lugs upon the adjacent tile whelt put in place. The re cesscs e are cut through to the rear side, as shown, so that whenput in place in front of the brick wall they will allow the ends of the Tnetal bindingstrips d, which project from such brick wall, to ii. in them, by which tiles is preserved.

is made of calcined plaster,

means a hollow space between the wall and In laying these tiles in the successive tiers a small quantity of thin putty of calcined plaster is applied to the exposed edges before the next tier is laid, which, in hardening, makes the whole a solid wall, and a small quantity of calcined-plaster putty is placed in the recesses c after they are engaged with the binding-strips, before the next succeeding series above is put in place, which prevents, when such plaster becomes harden ed, the binding-strips from becoming loosened;

D represents the tiles designed to be used in the building of partitions, and these are made of the same material and in the same manner as already described, but with channels 0 through them vertically, both front and rear faces being smooth. 'lhcse tiles. are laid in the same manner as already described, and in such manner that the vertical channels in one tier will be coincident with-the channels in the next vertical adjoining tier. These tiles 1') may have one or more openings, f, in such portions of the wall. as is prctelricd, for ventilating or heating purposes, such openings communicating with the -vertical channels through the blocks. A [tor the room has been finished with these blocks or tiles, the walls are rubbed down in any of the, known ways to smooth and polish them.

I t will readily be seen that in molding these tiles any desired style of ornamentation may be molded in their outtr faces, preferably such as w th not prevent or interfere with rubbing and polishing them after they are in place, so

that a hi ghly-ornamental wall can be furnished with very little comparative expense, without furring out from the outside walls, without studding, lathing, or plastering, and without theliability of cracking and becoming defaced, which generally attend walls 1nadein'theusual way, while they are ve'rmiirproof, and will makc a lluilding warm or more easilyheated than when constructed in the usual way.

I do not claim, broadly, the idea ofimaking building-blocks of plastic material with re cesscs to rccei ve projections on adjacent blocks, as I am aware that before.

\Vhat I claim as my invention is- 1. A block for inside walls, formed of cheap such blocks have bceh used lion {0 the lug on he adjacrtnt tile, substmr tinlly as described.

4. The block D, formed of cheap plastic nmvterinl faced on both sides with calcined. plastegr, with vertical channels P, lugs 71, and rcesses f; substantially as and for the purposes spellififiil.
